I just want to know if the game gets as broken when you buy the max amount of picrites as I thought Rumble World would become if I bought the max amount of poke diamonds. That was why I didn't buy any in the end. It was kinda fun to grind for those diamonds at first, doing the challenges, starting the game everyday to get them from my friends via spotpass and from strangers, getting some when you've met people on streetpass etc. Then I hit the paywall, now I need to grind a LOT just to get another baloon, or I can pay and then I probably won't have to grind EVER AGAIN. Which is the opposite extreme, game would become too easy at that point.
Similarly in Pokemon Picross, I like that there's the unlocking and other things, but I feel like it might become too easy to bypass that mechanic, essentially revealing its nature as a means to make you pay and nothing more.
I also don't like that I'm almost never rewarded for not using pokemon abilities. When the challenges require me to use them I just repeat the stage after finishing it on my own at first. But that's another story.
